Question about Craftsman 10.5 Hp 33" Commercial Cutting Width Zero Turn Lawn Mower
My commercial yazoo rider started to experience problem with left rear wheel not engaging when motion handle is moved forward or backword. after going forward and backward with right wheel moving the left wheel will kick in after about ten minutes. it makes a squeeking noise till it kicks in. i checked the spring and lines and they seem ok. a friend said it mifgt be the left pump going out , i hope not they are pricey. thanks
Im not a yazoo dealer but I can tell you some easy things to check, If you have a reservoir tank with an oil filter in line, there are two kinds of hoses suction and return if there is an air leak on a suction line it may not show an oil leak but it will put air into the pump making it week most of the time its cheap
hose clamps or loose hydro filter .
A lot of hydro use a gear case bolted right to the pump without any hoses , but that not what we call commercial .

Tips for a great answer:
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
Step 1- Place the rear of the mower safely onto jackstands on a level surface with engine off and parking brake set.
Step 2- Disengage transmission by placing freewheel control, located at the back of the frame, in the freewheeling position.
2a- Mowers with seperate pumps and wheel motors the freewheel is activated by turnign the bypass valves, one on each pump, two full turns.
The oil resevoir needs to be filled to the specifications listed in the owners manual before starting the purge procedure.
Step 3- Sitting in the operators seat(riders), start engine. After the engine is running, move throttle control to slow position. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 4-Move motion control levers to full forward position and hold for five (5) seconds. Move levers to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.
NOTE: During this procedure there may be some movement of the drive wheels, but they are not under load. The air is being removed from hydraulic drive system.
Step 5-Move motion control levers to neutral (N) position. Shutoff engine and set parking brake. Check and add oil as needed for units with an oil resevoir.
Step 6-Engage transmission by placing freewheel control into driving position, or by closing the bypass valves on the pumps.
Step 7-Sitting in the operators seat, start engine. After the engine is running, move throttle control to full speed. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 8-Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.
Step 9-Your mower is now purged and now ready for normal operation.For further information or assistance, we recommend contacting your lo
